Diamond Hole Saw for Porcelain Gres 25 mm GRAPHITE 57H287

The Diamond Hole Saw for Porcelain Gres 25 mm GRAPHITE 57H287 is a cutting tool designed to drill clean, round openings in hard ceramic materials such as porcelain tile and gres. With a 25 mm cutting diameter, this hole saw enables precise holes for pipe fittings, fixtures and cable pass-throughs. It is built for use with standard drills and can be applied with wet or dry drilling techniques depending on the substrate and working conditions.

Advantages

This diamond hole saw features a continuous diamond edge that provides consistent cutting performance on dense ceramic surfaces. Its construction reduces chipping and cracking around the hole, delivering a neat finish suitable for visible installations. The 25 mm diameter gives a standardized opening for many plumbing and electrical fittings, while compatibility with conventional drill chucks makes it easy to integrate into existing tool kits. The tool is suitable for both manual and powered drilling setups when correct speeds and cooling are observed.

Suitable for

• Drilling holes for pipes and plumbing fixtures through porcelain tiles and gres
• Creating pass-throughs for electrical cables in tiled walls
• Preparing openings for anchor sleeves and mounting hardware in ceramic surfaces

Key specifications

• Cutting diameter: 25 mm
• Cutting edge: diamond-coated rim for hard ceramic materials
• Material compatibility: porcelain tile, gres and other dense ceramics
• Intended mounting: standard drill chuck (fit depends on arbor used)
• Drilling method: suitable for wet or dry use depending on material and cooling

How to use

Secure the hole saw to a compatible arbor and tighten it in the drill chuck. Mark the drilling point on the tile and, if possible, start with a low-speed pilot to position the saw. Use steady, moderate pressure—avoid excessive force that could cause cracking. For wet drilling, apply continuous cooling with water to prolong cutting life and reduce dust. For dry drilling, work in short intervals to prevent overheating and check progress frequently. After cutting, clean the hole edge and remove any abrasive residue before installing fittings.

Usage recommendations

For best results on porcelain gres, begin drilling at a low speed and keep the cutting edge cooled. When working on large-format or thin tiles, support the tile from behind to reduce the risk of breakage. Replace the hole saw if cutting performance deteriorates or if the diamond rim shows visible wear.
